IMPROVEMENT IN BIRD-CAGES.

Specification forming part of Letters Patent No. 175,089, dated March 21, 1876; application tiled June 3, 1874.

this specification, and represent, in-

Figure 1, a front view, and in Fig. 2, a transverse section through one ofthe hoops.

This invention relates to an improvement in the manufacture Of wire bird-cages; and 1t consists in the method of uniting the vertical wires to the hoop by means of loops or'hooked rivets. i

The general o utline of the cage may be of any ofthe usual forms. The vertical wires a are made from Wire drawn in angular form,

preferably four sides, as seen in Fig. 4, thenv sides concave. This wire is twisted, as seen enlarged in Fig. 3.

By the use of this wire I am enabled to produce a much lighter cage than with the usual round wirethat is to say, the diameter of the wire across the angles being the same as the diameter of the round wire, the twisted wire is proportionately lighter. The twisting adds greatly to the transverse strength of the wire, so that the lighter wire is equally as strong as the greater weight of round wire. The twist may be regular or irregular, and, in addition to the decreased weight, the cage made from this wire presents a highly-ornamental appearance.

The hoops b are made from thin metal or wire, substantially Hat upon one side, and these are transversely perforated at the points where the vertical Wires are to pass, either with a single perforation, as at d, or two perforations, as at f. Into these perforations loops n of hook-form are passed, one end passing through and riveted, or of loop'form, as as at m, Fig. 2, the two `ends passed through the perforations; but in either case the loop surrounding the vertical wire and holding it in place. This enables the making of the hoops much lighter than can be done when the hoops are perforated `for the wires to pass through, and avoids the irregularity which must follow the soldering ofthe wires through the loop, and makes a much stronger and more perfect work than can be done by either of the heretofore-practiced processes. I

The feed-cup holders B are hung to a vertical post, C, and on this post is a coiled wire spring, D, one end, e, 0f which is hel'l fast to the cage, the other end 'i bearing upon the cup-holder, the tendency of the spring being to hold the holder in a closed position, then the opening of the holder winds the spring, and the reaction of the spring closes the holder.

I claim as my invention- The method herein described of securing the vertical wires to the annular hoops, consisting of the hooks or loops n m, encircling the vertical wiresv and riveted to the annular hoops, substantially' as specilied.
